Vaidya Metric:

Einstein’s theory of gravity is described by a set of complicated equations which use the mathematics of Riemannian geometry. It is very quite complex to implore what describe a physically interesting and practically realizable solution. In 1942, Professor Vaidya took up on this mission, and accomplished pioneering work which led to conception of such a solution. The result was The Vaidya Metric.

The Vaidya Metric:

Vaidya Metric applies to a set Einstein’s equations that describes the gravitational field of a star which has a sizable radiation.
